What the article says around this equation
in time that scales as , an exponential improvement in the matrix dimension N over the best classical algorithms available at the time, which scale roughly as N for a matrix with condition number [ 6 ] . What became known as the HHL algorithm is now routinely cited as the theoretical seed that later, explicitly labeled “quantum machine learning” proposals built their linear-algebra subroutines on top of.
